Domed area under Side Mirror - Damaged or Intended? - 67 Valiant

Mine is worse... I think is should be straight but I suspect they all were like that after leaving the factory because Bob who bolted on the mirrors needed to re-calibrate the torque on his wrench....
Thanks for the input. That was my thought too especially after seeing the little 'indents' from seemingly the washer being over tightened. It will be interesting to see if anyone else has an opinion or if it can be caulked up to Bob the Bolt Boy working thru anger issues!
